As the communication between the ninja world became more and more frequent, some high-level ninjutsu gradually spread.

The view of the portal still exists, and the inheritance of master and apprentice is still very valued, but it is not as serious as before.

Daimaru's use of wind escape to produce an illusion-like effect is not a great trick, but the development direction is just a little different.

Yeme's idea, Daimaru is still more supportive.

"If you can really do something refreshing, the future is limitless......

The secret art learned from others can only be considered one's own if it is thoroughly understood and integrated into oneself.

"Pioneering? I don't really understand that, but ......"

Yemu said tentatively,

"Maybe I can really find some special uses for polarized light killing arrays......"

"You're here to ask for advice? Obviously here to show off......"

Daimaru chuckled,

"If you have any ideas, don't beat around the bush, just show them directly, let me see......"

It's the mule, it's the horse that comes out and slips.

Although Daimaru's combat ability is not particularly strong, he thinks that his vision is not bad.

"Then you're good to go!"

Yeme's hands were sealed, and the air around them was constantly vibrating, and the faint light turned into colorful patterns like flowing water.

"It's ......"

Daimaru looked at this scene in surprise, slightly surprised.

"A small riverside ...... two kilometers away"

The glow of a fish swimming in the water, the owls cooing in the branches, the occasional bat skimming the water, and the mottled shadow of the moon on the ground......

All of this was presented in front of Oromaru's eyes, and in addition to being seriously dark, it was almost a reproduction of a flawless corner of a moonlit night.

"How did you do that?"

Light travels with a beginning and an end, and theoretically speaking, a ninja can control the scenery on the other end no matter which end they are in, provided that the chakra can influence that far.

With the strength of the night me, it is obviously impossible to manipulate the air from two kilometers away.

In the outdoors, where the light is good and there is less occlusion, Daimaru can observe it so far, but it is a little difficult to reproduce it up close.

Unless you can "transplant" the distant scene as it is, or use the light as paint, and depict it from scratch in the form of holographic projection in the vicinity.

The former is like a photograph taken by a point-and-shoot camera, and the latter is like a painter's sketch, both of which are almost impossible for Daimaru.

Yeme's strength is far worse than Daimaru's, and the proficiency of the polarized killing array is far inferior, so it shouldn't be the above two methods.

So......

"It's my talent......"

Yame blinked a little smugly,

"It's a ...... I'm proud of."

Also, even if Yeme's strength does not improve much in the future, he is also an unparalleled battlefield observer, as long as the environment is suitable, a radius of ten kilometers is within his observation range.

Under the background of such a technological level in the ninja world, the ten-kilometer reconnaissance area is really terrifying.

Even in the Fourth Ninja World War, such a perceptual ninja with special abilities is extremely rare.

"I didn't care much about it before, so you can still use your eyes like this......"

The human eye can produce vision, that is, light passes through the pupil, shines on the retina, stimulates the optic nerve, and the signal generated is transmitted to the brain, and after analysis, it generates stereoscopic perception.

It seems that the reflected light of the retina is reproduced in the vicinity by polarizing the light killing array.

"Probably similar to the principle of a movie projector......

Daimaru's thinking has always been about how to make the enemy invisible or see the wrong things; It is also quite useful for Yeme to be able to combine his own characteristics and think about the distant scenery that he can see and show it to others.

In the ever-changing battlefield, it is impossible to express all the details clearly in dry words, and it is naturally better to present them intuitively in front of the decision-maker.

However, the picture still looks too dim, both because of the lack of light at night and because of the lack of skill in night eye manipulation.

Through the transfer of countless small water droplets in the air, it is already rare to be able to restore it to the actual scene, and then it is difficult for some strong people to seek the "fidelity" of color.

"Those eyes of yours, are they the Blood Inheritance Limit?"

Yame replied:

"Probably not, none of my ancestors have heard of similar specialties, probably special abilities that were accidentally mutated......

"Hmm!"

Daimaru nodded.

The ultra-long-distance observation and perception of the eyes of the night eye is, to put it bluntly, the abnormality of the pupil and ciliary muscle of the eye, as well as the brain's super ability to process visual signals.

There are many strange people in the ninja world, and there are not a few strange abilities, but there are very few that are called the blood inheritance limit, and the most critical criteria are two:

One is that this specialty will be passed on with blood;

This is likely to be satisfied with the eyes of the night, and there is a great hope that their children and grandchildren will inherit this specialty.

Another condition is that chakra is required to activate or continuously consume chakra.

This one is still a little subtle.

However, Daimaru believes that Yame's eyes are not the limit of blood.

Because when the night eye ability is activated, the eyes and brain that theoretically function do not need to use chakra.

It's just that Yemu will still consume chakra if he uses his eyes for a long time to observe from a long distance, which is actually a lack of energy supply in the brain and needs chakra to maintain consumption.

This is equivalent to the fact that ninjas can run fast without using chakra, but if they want to run faster and farther, they need to consume chakra to bless themselves. But no matter how fast you run, can you say that this is the Ninja's Blood Inheritance Limit?

However, even if it's not the Blood Inheritance Limit, it's a valuable ability for the night eye.

After several generations of ninja development, it may not be impossible to research a new blood inheritance limit.

Seeing that Daimaru was deep in thought, Yame waited patiently for a while before seeing Daimaru raise his head.

"This usage is also effective in combat; You can perfect this method and discuss with Qian, how to cooperate with her illusion, maybe it will have a good effect......"

Perhaps, this would be a good ninja combo.

The scent illusion trap that continues to take effect, one accidentally will be hit, and it will get deeper and deeper; If you add the support of Yeme and set up a chain of illusions such as "Ghost Strikes the Wall", it may make the trapped enemies think that they have fallen into illusion and become afraid, revealing even greater flaws.

"This is what I think the polarized killing array is as it is, and if you add the virtual and real shadow clones, puppets, etc., it will be even more perfect......

It's a pity that Daimaru doesn't know how to do illusions, and it's hard to do so.
